I recently hit the 3 year mark of being tobacco free.Immediately I didn't even question the possibility that the evaporation/aerosol inhalation of two of the most commonly encountered food, cosmetic, and hygiene chemicals, glycerin and propelyne glycol, would be harmful whatsoever.I heard the hype, I asked doctors. 

There are things that they would be entitled to in terms of a price adjustment (in your example, if lumber prices skyrocketed for a specific reason beyond his control then usually the owner is on the hook, however, there are measures to limit this exposure).A contract can be drafted using the scope of work, estimate, and schedule (you can include liquidated damages - this is a sum (not a penalty) of what it would cost you if the project is not completed on time - think daily rent and storage rates). 

So here is my daily routine.

You could always do what some family members of mine do, build a dry-food stocked cabin in some remote location. 

I do this to put food on the table first.

Would i just refund them the daily rental amount for the days they cannot be in their units?

You may need a 5th electric meter and a 100 amp “house” panel installed to supply electric for new sump and any electric in common areas, exterior outlets, food lights, etc.This is what I need to do for a multi family building in the suburbs of Philadelphia.

You have to bring garbage out daily to the trash.

I've not yet done the math to determine which strategy would save me more money, but the big cons of this areNo primary residence, therefore slightly higher interest rates, 20 - 25% down (but depending on the market, this may very well be equivalent to 3.5 - 5% down in LA).Depends on the quality of tenant screening, but it's probably safer to assume that they won't take as great care of the property as I would.Probably need a property manager, professional or tenant.Either strategy seems to net me the same cost around $1,500 monthly, but I'm biased towards Los Angeles as I can rent to friends which solves a lot of the tenant/landlord issues.I'm not looking for anyone to give me all the answers but would appreciate any insight, food for thought, and constructive criticism. 

For instance, my renter was annoyed by the renters of the condo next store, college students, who partied to the early hours nearly daily.
